notes. You'll have to look in Thursday's notes (Sept. 14) notes
to find answers to the second two questions.
1. In (a) below, the air in the flask has the same temperature and
pressure as the air outside the flask. Based on what you see in
(b), is the does the air in the flask have HIGHER or
LOWER pressure than the air outside the flask. Would you
have needed to WARM or COOL the air in the
flask to cause this change in air pressure? Click here
if you really have trouble answering this question.
2.Explain (in words or with a sketch) how Galileo proved
that air has weight.
3. Before the pressure is plotted on a surface weather map, a 75 mb
correction must be made to the station pressure measured in
Tucson. Does the correction need to be ADDED to or SUBTRACTED
from the station pressure value? To convert to Greenwich Mean
Time (GMT) does a 7 hour time zone difference need to be ADDED
to or SUBTRACTED from the local time in Tucson?
4. Weather symbols #1 and #2 below represent a northern hemisphere
hurricane and a northern hemisphere tropical storm respectively.
What do you think symbols #3 and #4 are for? What do you notice
